[Problems to be Solved by the Invention] In such a conventional extrusion mold connection method for insulated cables, the conductor connection portion of the insulated cable is disposed within a certain mold cavity of the extrusion mold die. If the conductor connection part of the insulated cable is eccentric due to bending of the conductor connection part, the conductor connection part of the insulated cable will not be placed in the center of the mold cavity of the extrusion mold, and therefore the Since it is not possible to uniformly form the thickness of the extruded synthetic resin insulator such as polyolefin around the conductor connection part of the insulated cable to the required dimensions, there is a problem that the insulation properties at the conductor connection part are reduced. It was hot.

[Function] According to the above-described means of the present invention, the synthetic resin or the like is extruded around the conductor connection portion of the insulated cable in response to eccentricity of the conductor connection portion of the insulated cable due to bending caused in the conductor connection portion of the insulated cable. An adapter that forms an eccentric mold cavity so that the thickness of the insulator is uniform is set in the mold, and a synthetic resin insulator is extruded around the connection part of the conductor. The thickness of the insulator made of synthetic resin such as polyolefin around the connection portion can be uniformly formed to a desired size.

FIG. 1 shows an embodiment of the extrusion mold connection method for insulated cables according to the present invention. The outer periphery 7 fits into the cylindrical surface 4 of the extrusion molding die 5 formed on the large cylindrical surface 4, and the inside is adapted to the eccentricity of the conductor connection portion 2 of the insulated cables 1, 1' with respect to the outer periphery 7. The adapter 8 in which the eccentric mold cavity 3 is formed is set. Next, the eccentric conductor connection portions 2 of the insulated cables 1 and 1' are placed inside the mold cavity 3, and the adapter 8 is rotated along the cylindrical surface 4, as shown in FIG. The eccentric direction of the insulated cable 1 is adjusted so that the eccentric direction of the mold cavity 3 coincides with that of the insulated cable 1. Then, an extruder (not shown) extrudes polyolefin as an insulator into the mold cavity 3 to insulate and insulate the eccentric conductor connection portions 2 of the insulated cables 1 and 1'.

[Effects of the Invention] As explained above, the extrusion mold connection method for insulated cables according to the present invention includes arranging the conductor connection portion of the insulated cable in the mold cavity of the extrusion mold die, and forming the conductor connection portion of the insulated cable. In the extrusion mold connection method for insulated cables in which an insulator such as synthetic resin is extruded around the periphery of the insulated cable for insulated connection, a mold cavity is formed inside the extrusion mold die to accommodate the eccentricity of the conductor connection portion of the insulated cable. Since an adapter is provided for the insulating cable, the thickness of the insulator formed around the conductor connection portion of the insulated cable can be easily made to a uniform required size. Therefore, sufficient insulation is ensured at the conductor connection part, and
It has excellent effects such as being economical because the amount of synthetic resin used for the insulator is optimized.
